Often known as "fracing", involves pumping a fluid into the well at very high pressure to create cracks in the reservoir rock. Sand or other material may be used as the "proppant" to prop open the gaps created by fracing.
A well stimulation technique in which fluids are pumped into a formation under extremely high pressure to create or enlarge fractures for oil and gas to flow through. Proppants such as sand are injected with the liquid to hold the fractures open.
A process of opening up underground channels in hydrocarbon-bearing formations by force rather than by chemical action such as in acidizing. High pressure is hydraulically or explosively directed at the rock, causing it to fracture.
A procedure undertaken to attempt to increase the flow of oil or gas from a well. A fluid (usually crude oil,, diesel oil. Or water) is pumped into the reservoir, with such great force that the reservoir rock is physically broken and split open. Usually the 'frac fluid' carries small pellets or beads mixed in with it; the idea is for them to get caught in the fractures and prop them open (the beads or pellets are called the propping agent or proppant). As the pumping pressures are gradually released at the surface, the natural reservoir pressures will force the 'frac fluid' out of the reservoir, and back into the well. This procedure is also called hydraulic fracturing. 'To frac a well' means to hydraulically fracture a reservoir in a well.
Breaks in the rock, the openings of which allow mineral-bearing solutions to enter. A "cross fracture" is a minor break extending at more-or-less right angles to the direction of the principal fractures.
The practice of pumping special fluids down the well under high pressure; fracturing causes the formation to crack open, creating passages for the reservoir fluids to flow more easily into the wellbore.
a method of stimulation production by opening new flow channels in the rock surrounding a production well by pumping proppant and fluid into the well at high pressure and volume.
The process of cracking open the rock formation around a well bore to increase productivity. This is normally done by applying hydraulic pressure down the well bore.
A method of breaking down a formation by pumping fluid at very high pressures. The objective is to increase production rates from a reservoir.
application of hydraulic pressure to the reservoir formation to create fractures through which oil or gas may move to the well bore.
A method of stimulating well production by increasing the permeability of the producing formation. Fracture fluids, which include propping agents such as, sand or glass beads, are pumped into the formation under extremely high hydraulic pressure. The propping agents facilitate the formation of channels to release water and gas into well.
The technique of improving production or injection rates of a well by pumping a mixture of fluids into the formation and rupturing the rock, creating an artificial channel. As part of this technique, sand or other material may also be injected into the formation to keep the channel open, so that fluids or gases may flow more easily through the formation.
Pumping fluids down a well at high pressure to create cracks in the formation that will allow natural gas to flow more freely
